i want to show a % discount box on the center of the browser when somebody clicks the close button of the browser window . I have tried the
window.onbeforeunload = function (e) {
};
function formSubmit() {
window.unbeforeunload = null;
}
function but it opens the browsers own dialogue box, how can i customize it? or better, how can i open my own box? so that i can change the position and style of it.
Any help will be greatly appreciated,
Thank you,
The onbeforeunload event is the only event that fires (besides the onunload event, but don't use this) before the window leaves the page. The onbeforeunload event is special because it is the only event that will automatically be fired off once the user tries to leave the page, but has the option of staying on the page if the user clicks cancel.
So, to directly answer your question, if the user closes the window, hits the back button, or navigates to a new URL, you will have to use the onbeforeunload event. You can add text inside of the pop-up, but some of the default text will always stay there. You just have to return a string.
Now, if the user were to click on a link that is a part of your application or tries to log out, you can anchor an event to that, which could make a window pop up that has the "% discount box". The reason you can't anchor an event to the back button, external URL, or the close window button is that they don't belong to your application. So once they click one of those, the browser goes off on its way with nothing you can do, except for the onbeforeunload event.

I'm trying to save some data when the popup closes, but I can't find a place to add a listener.
There was an earlier post suggesting this in the background page, but it doesn't work:
chrome.runtime.onConnect.addListener(function (externalPort) {
externalPort.onDisconnect.addListener(function () {
console.log("onDisconnect")
})
console.log("onConnect")
})
Not even the onConnect listener is working.
Any ideas on how to get it to work>
I actually took a different approach. Instead of listening for events, I move the state to the background page. So when the popup opens up it reads the state form the background page and the user can continue where he/she left off.
this is probably dead easy but I can't find a solution. I made a dialogue system and have a UI-button to click when the player should display a sentence next.
The issue is that the button is only triggered onMouseclick and I would like to change the input button to Enter. Would anyone know how to go about this?
If you need to determine if the button is selected first or not, I suggest you take a look at this page: https://docs.unity3d.com/ScriptReference/UI.Selectable.IsHighlighted.html
If you don't want pressing the button to have any functionality, you just wouldn't link it to any functions.
Working code might look something like this:
public class selectableExample : Selectable{
BaseEventData _event;
void Update()
{
if (IsHighlighted(_event) == true)
{
if (Input.GetKeyDown("enter")){
print("replace me with working function"); // whatever you want to have happen on button press
}
}
}
}
You simply attach this to your button and it should respond the same as being pressed. To be honest, it hardly seems like you actually need a button at all for this though, you'd probably be fine with just a label telling the player to press "Enter" and then simply checking for that input.
You can use the Event Trigger component to use one of the many event types. Select Submit (this is set to enter and return in the input settings at edit>project settings>input by default).
Don't set anything in the OnClick event.
The only thing needed now is to actively highlight the button from somewhere with ReferenceToButton.Select().
I am newbie to MFC. I have a native C++ MFC app. I want to show a dialog from main dialog. In the main dialog I am having three button (Back, Next, Cancel) respectively.
On the Next button click event I am calling DoModal to show another dialog by hiding the main dialog as follows,
void CFirstPage::OnBnNextButton()
{
::ShowWindow(this->GetSafeHwnd(),SW_HIDE);
CSecondPage secondDlg;
secondDlg.DoModal();
}
void CSecondPage::OnBnBackBtnClicked()
{
::ShowWindow(this->GetSafeHwnd(),SW_HIDE);
CFirstPage FirstPage;
FirstPage.DoModal();
}
After executing this code snippet, the main dialog got hidden and even the application icon also disappears from the taskbar and again appears when the other dialog pops up.
(Basically I am having the same icon for both the dialogs, the icon should not get disappeared and appear again. It has to remain same without appearing and disappearing .)
How can show the icon in the taskbar without any flickering effect?
During traversing from back to next in middle I clicked cancel and the Cancel event is handled as follows,
void CFirstPage::OnCancel()
{
CDialog::EndDialog(TRUE);//For closing the dialog.
}
void CSecondPage::OnCancel()
{
CDialog::EndDialog(TRUE);//For closing the dialog.
}
Steps1:Click Next in the main dialog
Step2: Click Cancel in the second page
Now the application closes. But still instance is active in the "TaskManager". As per my understanding no instance should be alive once windows is closed ?
I suspect as the first dialog is only hidden not ended that instance is still existing in the TaskManager. Is this understanding correct?
How can I resolve this issue?
Can anyone kindly help me to resolve this issue.
As said by Iinspectable property sheets are best suited for your your problem statement.A very good example on how to use CPropertysheets can be found in codeproject
CProperty sheet example
Probably your main windows is still hidden after you end dialog with second page. Ending dialog of CSecondPage does not close application only closes active CSecondPage dialog.
Also OnCancel/OnOK does not need to be overriden if you just EndDialog with it. There is default behaviour implemented in OnCancel, which will close the dialog.
After secondPage.DoModal() show your main dialog again, or close it if that is the behaviour you want to achieve.
FirstPage isn't the original first dialog now, so you should store the first dialog object by yourself. You can do that like this:
void CFirstPage::OnBnNextButton()
{
::ShowWindow(this->GetSafeHwnd(),SW_HIDE);
CSecondPage secondDlg;
secondDlg.setFirstDialog(this); //customer function to store first dialig object
secondDlg.DoModal();
}
void CSecondPage::OnBnBackBtnClicked()
{
::ShowWindow(this->GetSafeHwnd(),SW_HIDE);
::ShowWindow(m_firstDialog->GetSafeHwnd(), SW_SHOW);
}
I've seen plenty of information about this topic, but not the answer to this question exactly. I have the opposite problem of most. I want to prevent the Enter button from clicking a button when the button has focus. And to do this, I don't want to simply disable the button from accepting an Enter button press, but rather I want to conditionally capture the Enter button press in a callback method. Right now, I have bound the following event to all widgets in my python program:
parent.Bind(wx.EVT_CHAR, self.CharInputCallback)
The EVT_CHAR event is actually thrown when the enter button is pressed and I'm able to get the callback in my callback method. My problem is that the enter button's functionality of virtually clicking a button still goes through, despite purposely not skipping the event (which would forward on the event). Since this is happening, and I'm sure my callback method is not forwarding the event along (I've tested this by capturing characters going to a text box) I suspect that the enter button throws an additional event that I'm not capturing. I've tried binding and capturing the additional following events to prevent the "virtual click" from the enter button:
parent.Bind(wx.EVT_TEXT_ENTER, self.CharInputCallback)
parent.Bind(wx.EVT_KEY_UP, self.CharInputCallback)
parent.Bind(wx.EVT_KEY_DOWN, self.CharInputCallback)
Yet when I press enter, the button in focus is still clicked. To summarize, is there an additional event being thrown when I press the enter button? If so, which event in particular is "virtually clicking" the button? Most forums I've found have discussed how to recognize when the enter button is pressed, but I want to recognize it and disable it's default action when a button is in focus.
I tried binding all those events to different handlers and I also bound EVT_BUTTON. It appears that EVT_BUTTON always fires BEFORE the key and char events do. If you don't want your button to be clicked, then you'll probably have to either disable it, use a different widget (maybe one of the generic buttons) or create your own. I would also ask on the wxPython mailing list to see if they have any suggestions.
The only way to order the events in wxPython that I'm aware of is to use wx.CallAfter or wx.CallLater. I'm not sure how you'd use that in this context though.
The event that causes enter to click a button is the key up event. My code for my callback was messed up slightly. Capturing the key up event and not skipping it prevent the enter button from clicking a button in focus. On Windows 7 anyways.
I have referred this for creating error message tool tips, to be displayed continuously unless the error is resolved by the user. :: http://aralbalkan.com/1125 .....................
But, this is being applied to a pop-up window visualized as a pop-up form.
When the user clicks 'CANCEL' button, I want the error message tooltips if present to be cleared off from the screen. The message tool tips remains on the screen even if the CANCEL button is clicked.
The tooltips created are not linked to the dialog pop-up directly - i.e. they're not created as child widgets of the pop-up.
To work around this you hook into the cancel button with an on-click hander, and have the handler loop through all elements in the errorMessageToolTips dictionary, hiding each one.
Depending on your code structure, to avoid problems later on you may want to make the errorMessageToolTips dictionary specific to the pop-up and not a global array.
